The measure of ∠bcd is 120°. the measure of ∠abc is 85°. what is measure of ∠bac?

35°

Step-by-step explanation:

<BCD + <C = 180° (angle on a straight line )

120° + <C = 180°

<C = 180° - 120° = 60°

<BAC + <ABC + <C = 180° (sum of interior angles of a triangle)

<BAC + 85° + 60° = 180°

<BAC + 145° = 180°

subtract 145° from bothsides

< BAC = 180° - 145° = 35°

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
